IntroductionWater scarcity is a growing problem, with estimates showing that 40% of the world’s population could face water shortages by 2030. This issue is even worse because only 3% of the Earth’s water is freshwater, while 97% is seawater. Finding better ways to save and use water is critical to solving this problem. At the same time, renewable energy is essential for reducing carbon emissions
This paper is part of an ongoing research on the trajectory of rhetoric of political reforms in Bahrain during the past 10-years of reign by king Hamad bin Isa. Within less than two years of his reign, the king abandoned his wide ranging blueprints for political and institutional reforms designed to end to a decade-long civil unrest. I argue that the king continues to use, albeit more creatively,
Popular Abstract in Swedish Lars Ahlin har en central position i den svenska litteraturen. I forskningen framträder bilden av hans författarskap som ett litterärt projekt präglat av en jämlikhetsvision, ett motstånd mot språkliga, existentiella och politiska hierarkier. Det ahlinska berättandet är ett sällsynt gott exempel på hur ett litterärt projekt också kan vara etiskt bestämt. Detta samband bAs my title indicates, this dissertation is oriented towards two academic subjects: Ethics and Literature. Of late, the borderland between these two disciplines has attracted international scholarly attention. Within ethics, literary works are becoming a primary material; conversely, the study of literature has taken on ethical issues. As a result, the potentially referential character of fiction
Popular Abstract in Swedish Depression är ett allvarligt och potentiellt förödande hälsoproblem som drabbar flera miljontals människor i världen. Trots framsteg inom depressionsforskningen återstår flera frågor kring varför vissa individer upplever depression, och andra inte, och varför vissa blir hjälpta av behandling, och andra inte. Den forskning som rapporteras här tar som utgångspunkt hypotesDepression is a serious and potentially devastating health problem, impacting millions of individuals worldwide. Although advances have been made in depression research, there remain a number of outstanding questions as to why certain individuals experience depression and why some respond to treatment and others do not. The present research takes a starting-point in the hypothesis that the existen
Extended abstract Recent studies point at significant and ongoing technology induced changes in the retail landscape, creating new and interesting research avenues, new managerial challenges and a need to rethink existing business models (e.g., Burt and Sparks 2003; Kollmann et al., 2012; Sorescu et al., 2011). This paper aims at contributing to the literature concerning the managerial aspects th
BACKGROUND: The Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) provides a comprehensive assessment of risk factor exposure and attributable burden of disease. By providing estimates over a long time series, this study can monitor risk exposure trends critical to health surveillance and inform policy debates on the importance of addressing risks in context.METHODS: We u
Background: In many parts of the world, roadsides are regularly managed for traffic-safety reasons. Hence, there are similarities between roadsides and certain other managed habitats, such as wooded pastures and mown or grazed grasslands. These habitats have declined rapidly in Europe during the last century. For many species historically associated with them, roadsides may function as new primary
Background: Many with a mental illness have an impoverished everyday life with few meaningful activities and a sedentary lifestyle. The study aim was to evaluate the effectiveness of the 16-week Balancing Everyday Life (BEL) program, compared to care as usual (CAU), for people with mental illness in specialized and community-based psychiatric services. The main outcomes concerned different aspects
Land-use and land-cover (LUC) changes are a key uncertainty when attributing changes in measured atmospheric CO2 concentration to its sinks and sources and must also be much better understood to determine the possibilities for land-based climate change mitigation, especially in the light of human demand on other land-based resources. On the spatial scale typically used in terrestrial ecosystem mod
'If you read only one book on the English language-read this one. English - One Tongue, Many Voices covers all aspects of the English language: its global spread, international and local varieties, history from obscurity to primacy, usage and uses, standards and creoles, style and change in progress, politics and controversy. The scope of the book is vast, its depth impressive, and its balance adm
Kulturlandskapet är starkt knutet till människan och hennes aktiviteter. Flera tusen år av samspel mellan människa och natur har skapat landskap som definierar levnadsvillkoren för en mångfald av arter. Men när samhället förändras, förändras även kulturlandskapet. De forna årtusendenas långsamma och gradvisa förändringar har accelererats av människans teknologiska framsteg. I södra Sverige har jorIn this thesis, I explore the relationships between structural and compositional landscape properties, and species diversity, using remotely sensed data on a variety of spatial scales. The thesis shows that increased landscape heterogeneity, measured using environmental and spectral variables that were used both separately and combined, is generally positively related to plant species richness. I
Flyktingar, speciellt de som varit utsatta för tortyr och annan form av organiserat våld, upplever ofta en rad olika svårigheter, inklusive posttraumatiskt stressyndrom (PTSD), depression och somatiska symtom, särskilt smärta. Multidisciplinär behandling har utvecklats för att handskas med denna komorbiditet hos flyktingar, som har påvisat medelhöga effekter.Det huvudsakliga syftet med denna avhanRefugees, particularly those exposed to torture and other forms of organized violence, often experience a wide range of difficulties, including posttraumatic stress disorder (PTSD), depression, and somatic disturbances, particularly pain. Multimodal treatments have been developed to target this comorbidity in refugees, with evidence suggesting they are moderately effective.The overall aim of this
Background: In todayʼs fast moving world, the communication of science and technology is playing an increasingly important role for the relation between science and the public. Both journalists and researchers have their own agenda when communicating as public interest, corporate science and the competition for funding increases. At the same time, the conditions on which stories about science can
Conventional dairy sections are often small and most customers pass through them quickly. Arla saw this as an under-utilisation and launched a new concept called Dairy Square. This is a store within the store where the temperature is lower, the environment more pleasant for the customer and the interior specially designed to increase sales. The concept has so far been a success. Arla have complet
Abstract: The physiological responses of two Hong Kong acorn barnacles, Tetraclita japonica and T. squamosa differed under identical heat stress conditions. Both species experienced increased body temperature and mantle water osmolality with higher temperatures and prolonged emersion time. Species comparisons however, showed that T. japonica had warmer body temperatures and more concentrated osm
Streptomyces belong to the phylum Actinobacteria, which are Gram-positive bacteria with GC-rich DNA. Most Streptomyces are strict aerobes and inhabit soil. They are known for production of a wide range of secondary metabolites, including antibiotics e.g. the macrolide erythromycin (S. erythraeus) or chloramphenicol (S. venezuelae). The typical smell of wet soil is owed to geosmin, also a secondary
It’s clear that human activities have heated our climate via the release of anthropogenic greenhouse gases. Recent changes within the earth climate are rapid, intensifying, and unprecedented. With each additional increment of warming, climate change is impacting ecosystems through changes in average conditions, climate variability, coupled with other associated changes such as biodiversity loss an
Information technology is in common use in our society and has affected government offices around the world and in Sweden as well. This has created a whole new form of administration that uses computerised aid in handling areas that generate a big amount of cases. Earlier examples of this within the Swedish administration is the tax authority's tax return through the Internet or by SMS and the
